Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space.
In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.
Radio waves were discovered before the radio was invented.

In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
no, mechanical waves are not radio waves
Radio waves ARE electromagnetic waves.

No. Radio waves were discovered around 1880. The first radio stations began about 1920..

None of them. They were all discovered a good many years ago.

Transverse. Radio waves are electromagnetic waves, which are transverse.
